Founded in 2022 in Santa Barbara, California, by materials scientist Eric Pressly—the co-inventor of Olaplex's original bond-building technology—epres represents the next generation of molecular hair repair. Pressly launched the brand to simplify the often complex bond-repair category, focusing on high-performance, acid-free formulas that deliver professional-grade results in a single step. The brand's signature Biodiffusion Technology uses oil-based molecules that continue to repair broken disulfide bonds even after the hair has dried, distinguishing it from traditional water-based treatments.
